Fecha de publicación: 22/12/2023 Fuente: Wipo "IOT" The utility model relates to a heat dissipation mechanism of an IOT module, which comprises a box body, a box cover is arranged on the top surface of the box body, the heat dissipation mechanism is arranged on the box body, the heat dissipation mechanism comprises an IOT module body, the IOT module body is placed on the inner bottom wall of the box body, fixing blocks are fixed on the front surfaces and the back surfaces of the left side and the right side of the IOT module body, and the fixing blocks are fixed on the front surfaces and the back surfaces of the left side and the right side of the IOT module body. The sides, away from the IOT module body, of the fixing blocks are in threaded connection with bolts, the ends, away from the fixing blocks, of the outer surfaces of the bolts are in threaded connection with nuts, and the heat dissipation mechanism further comprises limiting grooves formed in the front ends and the rear ends of the left side and the right side of the top face of the box body. Heat generated in the working process of the IOT module body can be discharged in time through the cooling fins and the cooling holes, the cooling efficiency is improved, circuit elements on the IOT module body can be effectively protected, in addition, the IOT module body can be fixed in the box body through cooperation of bolts and nuts, and the box cover plays a role in protecting the IOT module body.
